f 0 all 20 7mm it may concern:

Be it known that 1, WILLIAM H. C. Hun-ANN, Jr, a citizen of the United States, residing at Snyder, in the county of Dodge and State 01? Nebraska, have invented new and useful improvements in Wheel-Guards for lVheeled Disk Harrows, of? which the My present invention has for its object to practically improve wheeled disk. harrows by the provision of a guardfor one of the ground wheels of the harrow, calculated'to effectively prevent the disk adjacent tothe wheel from catchin into the s Jokes oi the latter and breaking the same. 7

To the attainment of the foregoing the invention consists in the improvement as hereinafter described and definitely claimed. In the accompanying drawings, hereby made a part hereof:

Figure l is a general view illustrating wneeled disk harrow one of the ground wheels of which is equipped with' my improvement. p

Fig. 2 is an enlarged detail view showing the arrangement of my novel guard rela tively to the wheel that carries the same and the adj accnt disk of the harr w.

Fig. 3 is an enlarged detail view showing;-

the preferred specific connection of the wheel guard to the spokes oi the wheel.

Similar numerals of reference designate corresponding parts in all or" the views of the drawings.

In general the harrow is of the ordinary well known construction, including a frame 1 groups of disks 2 and ground wheels 3.

In furtherance of my invention the ground wheel 3 at the right of the harrow is provided with an annular guard t, the function oi which is to preclude or prevent the adjacent disk or disks from catching against the spokes 5 of the wheel with a view to averting breaking of'the said spokes. The said annular guard which is preferably of metal spokes.

prefer to employ a shackle 6 the bight of which is arranged in an aperture 7 in the guard 4, and the threaded ends of which are arranged at'opposite sides of one spoke 5. and carry a plate 8 that is clamped against the outer side of the spoke through the medium of nuts 9 mounted 011 the threaded end portions of the shackle.

Manifestly novel guard is susceptible of ready application, and when properly applied as shown between the wheel and an adjacent disk or disksis calculated to effectively avoid breakage of the spokes by a disk or disks.

, Having described my invention, what I claim and desire to secure by LettersPatent, is

1. The combination with a ground wheel and a disk of a wheeled disk harrow, of an annular guard to protect the spokes of the ground wheel from the disk or disks; the said guard being fixedly connected to some of thespokes of thewheel and being interposed between the spokes and the disk or disks;

2. The combination with a ground Wheel and a disk of a wheeled disk harrow, of an annular guard to protect thespokes of the ground wheel from the disk or disks; the said guard being formed of metal and extending laterally inward from the spokes against which its outer'edge is arranged and being provided with apertures, shackles arranged with their bights in said apertures
